DNS filtering solutions are a reliable line of defense against cyberattacks for your company.

The attack surface has grown as more people use cloud computing, IoT devices, and internet services globally.

Furthermore, remote work is becoming more and more common, and you have no idea how secure your contractors’ and employees’ devices and networks are.

In the meantime, hackers are becoming more skilled and creative in their methods of breaking into systems, networks, and data. They even outlive technologies like firewalls and antivirus programs.

This is where your networks, data, devices, and remote workers can all benefit from enhanced protection offered by DNS filtering services like SafeDNS.

We will learn about DNS filtering and its advantages in this article.

Let’s get going!

What Is a DNS?

A domain name, like TopReviewHostingASP.NET, is matched to an IP address using the Domain Name System (DNS).

An identification string for a device in a network, an IP address is a lengthy and distinct set of digits and characters. It can be difficult to remember addresses like, 2001:db8:0:1:1234:0:567:8:1, etc.

DNS simplifies this process by linking a web domain name to its IP address, facilitating users’ access to websites across the internet.

It functions similarly to a phonebook or contact list on a smartphone, saving users from having to memorize complicated IP addresses. Rather than manually dialing each number, you can store your contact phone numbers on your smartphone and make calls just by tapping them.

Your device will initiate a DNS query as soon as you enter the domain name of a website into your browser. In order to match the requested domain name to an IP address by examining the cache or contacting additional DNS servers, it will forward this query to a unique web server known as a DNS resolver.

This process, called “domain resolving,” occurs when the DNS server responds to your device with the correct IP address. At last, the IP address-related server can be contacted by your device.

The requested website’s content will load as a result of this helping to establish the connection. Although it may seem like a long process, all of this happens in milliseconds, allowing you to access a website quickly.

What Is DNS Filtering?

DNS filtering is the process of using code to weed out unwanted or hazardous content and blocking or restricting malicious websites. It aids in protecting your assets, network, and data from online threats.

Furthermore, DNS filtering enables more thorough visibility into who has access to what kinds of data and improves access controls within an organization.

Numerous software programs with DNS filtering features are available today. These are referred to as DNS filtering services or solutions (SafeDNS, for example).

How Do Services for DNS Filtering Operate?

A specially configured DNS resolver functions as a filter for each DNS query that is sent to it. It refuses to answer the query and prevents users from accessing the requested websites if it finds a suspicious domain.

DNS resolvers keep track of a blocklist and use it to determine whether a user or domain name appears suspicious. The DNS resolver will block a domain name if it is on this list; if it is not, the domain name’s request to allow access to the site will be granted.

In addition to having this capability, domain filtering services can keep an allowlist updated so that only the domains included in it are allowed while all others are blocked. By turning on a DNS filtering service, you can evaluate all incoming and outgoing internet traffic and let only secure traffic through your network.

Between the requested web page and the IP address making the request, these services filter web traffic. The request will be filtered according to a number of categories, including social media, news channels, phishing schemes, malicious websites, and unsuitable websites. The ones that appear dangerous or suspicious will then be blocked.

For example, assume that your company’s network has a DNS filtering solution installed. When an employee clicks on a malicious link they received in the mail, the request is routed via your DNS filtering service to the DNS resolver, rather than the malicious website. If the malicious website is found on the DNS resolve’s blocklist, the request will be blocked, thwarting the attack.

Why Is DNS Filtering Necessary?

Cybersecurity attacks are a global concern for both individuals and businesses. Without the need for human intervention, hackers can initiate malicious campaigns by using network ransomware and advanced technologies. They try to get past the security measures in place at your company in order to steal data, hack your accounts, make financial threats, and other things.

As a result, you need to be ready for any kind of cyberattack at all times.

  • Malware: Spyware, worms, ransomware, viruses, trojans, etc. could be among them. When malware takes advantage of a vulnerability to get past security measures, it can do so by downloading email attachments or clicking on dubious links.
  • Phishing attacks: These often occur when malevolent actors pose as trustworthy sources and bombard users with numerous malicious emails. It can be whaling to stakeholders and staff, pharming to any user, and spear-phishing to businesses and individuals.
  • Man-in-the-middle attacks: It happens when someone snoops on a transaction going on between two people in order to alter or steal data.
  • Denial-of-Service attacks: In order to overwhelm bandwidth and resources, web traffic is flooded into networks, systems, and servers. It opens the door for additional cyberattacks.
  • SQL injections: It happens when malicious code is introduced into a system or server using SQL language, forcing the server to divulge protected data.
  • Zero-Day attacks: It involves taking advantage of a weakness that arises when security patches for a network or system are still pending release.

Additional forms of attacks include rootkits, IoT attacks, cross-site scripting, and password theft.

Thus, you need to always be ready with strong security tools to repel these lethal cyberattacks if you want to protect yourself from them. And one excellent method for doing so is DNS filtering.
